I can't believe that only salsbr posted the obvious reason.

Your vehicle is not yet "broken in". Nothing you do will make the slightest difference for the first few thousand miles. You will likely see a gradual increase once you hit 3,000 and better as you get to 5,000. Even the manual says not to look at your fuel economy for the first xxxx miles.

That's not to say you shouldn't try as you will learn the techniques for when it does matter.
